Hello!
We are in the process of upgrading our servers and applications to newer versions. We are currently running Openfire 3.9.3 on an Ubuntu 12.04 box which also hosts our email server. The goal is to get the server upgraded to Ubuntu 14.04 and have it fully patched. I would also like to update Openfire to the latest version, as well. Our database is being run on another physical server which hosts MySQL 5.6. I had a few quick questions to hopefully get this done as smoothly as possible with limited down time.
1. Which package do I download to upgrage? I'm assuming the openfire_4_0_2.tar.gz but wanted to confirm.
2. Would it be more efficient to upgrade Openfire before or after the upgrade to Ubuntu 14.04?
3. Finally, if I run sudo apt-get upgrade as well as a sudo do-release-upgrade is there any packages which I should not upgrade? Will either of these commands break Openfire by upgrading the Java packages?
Thanks!
